Hi, some of you will know that i have been suffering from daily headaches for around 4 months now. Ive had blood tests which were fine. Ive tried everything from tiger balm to different medications but nothing really works. As its been going on so long do i have the right to ask for an mri scan ? Im also feeling sick and dizzy, i just dont feel right at all. Im sick of being fobbed off with different medications that dont work.
